There are lots of old buildings in Hong Kong. I think the most interesting ones are the corner buildings with a round corner on every floor. These buildings are pretty old, and most are not tall at all. I would guess they are 50 to 60 years on average. I hope they will preserve these buildings are they are much more interesting than the new taller highrises built these days. Here are some photos of the corner houses I took while I was in Hong Kong.
